Coupled ferroelectricity
Web摘要： We present a first-principles investigation of ferroelectricity in layered perovskite oxide La 2 Ti 2 O 7 (LTO). Our calculations indicate that LTO's high-temperature (1770 K) ferroelectric transition results from the condensation of two soft modes that have the same symmetry and are strongly coupled anharmonically.
